Borosil Thermo Vacuum Flask – 500 ml (Steel/Silver) (Grade 304 SS, 24-Hour Hot & Cold)
The Borosil Thermo Vacuum Flask – 500 ml in Steel Silver is a vacuum-insulated stainless steel flask from Borosil's Hydra range — a classic, professional steel-silver exterior with a matching carry jacket for office and travel use. Constructed from Grade 304 (18/8) food-grade stainless steel inside and outside, the flask is rust-proof, odour-free, and non-reactive with any hot or cold beverage. Its copper-coated double-wall vacuum interior keeps beverages hot or cold for up to 24 hours — a performance level suited to long office shifts, travel days, and outdoor use. At 500 ml, it carries enough for multiple servings without needing a refill, and the cap doubles as a convenient drinking cup. Borosil provides a 1-year warranty on this flask against manufacturing defects.
The Borosil Thermo series features a distinctive carry jacket that can be adjusted for both horizontal and vertical carry — a practical design feature for those who pack their flask in a bag on its side or slip it into a bag pocket upright. The flip-top lid is leak-proof and enables controlled pouring without fully removing the cap, reducing spill risk during movement. To maximise performance, Borosil recommends pre-conditioning the flask with hot water before filling for hot beverages, or with cold water before cold use. The flask is not suitable for carbonated drinks. The brushed steel silver finish gives it a clean, stylish appearance suitable for offices, hospitals, travel, and daily personal use.
Key Features
Grade 304 SS with Copper-Coated Double-Wall Vacuum Insulation
Food-grade 18/8 stainless steel inner and outer walls combined with copper coating and vacuum insulation deliver up to 24 hours of hot or cold temperature retention. The exterior stays condensation-free, preventing wet bags and surfaces during carry.
500 ml Capacity — Multi-Serving Hydration
The 500 ml capacity holds enough for several cups of tea, coffee, or water — suitable for a full morning of office work, a day's worth of travel sips, or multiple servings at a picnic without needing to refill.
Flip-Top Leak-Proof Lid with Cap-as-Cup Design
The flip-top lid is leak-proof for safe bag carry, and the cap unscrews to function as a drinking cup — a practical, no-extra-crockery feature for sipping tea or coffee on the move.
Unique Adjustable Carry Jacket — Horizontal or Vertical
The carry jacket that comes with this flask can be oriented for both horizontal and vertical carry — ideal for those who carry their flask in a bag pocket upright or slung over a shoulder in a flat position.

All plastic components are BPA-free; the steel body is rust-proof and food-safe. Borosil provides a 1-year warranty against manufacturing defects, backed by the brand's customer care network across India.
